Yes,

would seem to indicate that it is 66/66.  The latency is my fault, I set it
manually
to see if it would help performance.  Unfortunately I don't think the E1000
with
will with the AMD chipset, and I don't think Intel will be releasing a fix
somehow.
Do you have access to an AMD760MPX ?  I would love it if someone could
verify
this is a working combination before I go out and spend more money.

Are you sure your tg3 NIC is 66/64 PCI?  For 66/64, try an e1000 NIC, you
should be able to get 800Mbps or better out of it on such a system.
